例1:
class UserInfo(models.Model): nickname = models.CharField(max_length=32) username = models.CharField(max_length=32) password = models.CharField(max_length=64) gender_choices = ( (1,‘男‘), (2,‘女‘), ) gender = models.IntegerField(choices=gender_choices)
ralated_query_name
class U2U(models.Model): g = models.ForeignKey(‘UserInfo‘,ralated_query_name=‘a‘) b = models.ForeignKey(‘UserInfo‘,ralated_query_name=‘b‘) # ralated_query_name # obj.对象男.b_set.all() # obj.对象女.a_set.all()
ralated_name
class U2U(models.Model): g = models.ForeignKey(‘UserInfo‘,ralated_name=‘a‘) b = models.ForeignKey(‘UserInfo‘,ralated_name=‘b‘) # ralated_name # obj.对象男.b.all() # obj.对象女.a.all()
例2:
反向查找
class UserType(models.Model): title = models.CharField(max_length=32) class User(models.Model): username = models.CharField(max_length=32) ut = models.ForeignKey(‘UserType‘,related_name=‘xxx‘) ## related_name=‘xxx‘:
反向:小写表名user_set ===>xxx
## related_query_name = ‘xxx‘ 反向:user_set==>xxx_set
推荐使用
ut = models.ForeignKey(‘UserType‘,related_name=‘users‘)
related_name和related_query_name举例区别
